1 - Polarization and UV Protection
Polarization is nowhere remotely associated with UV protection – the two phenomena are mutually exclusive. Our polarized lenses are made from Triacetate Cellulose (aka TAC) which is a multi-layered lens technology that is formulated to provide complete and thorough elimination of glare and harmful UV rays. They provide 100% protection against UVA, UVB & UVC rays up to 400 nanometres.As for our safety lenses, they are made from polycarbonate materials. This material is also known to have UV blocking properties.

2 - Are Polarized Sunglasses Worth It?
As with all things in life, the answer is very much dependent on what you plan to use it for. Polarized sunglasses are especially worth it if: You are mostly on the road when the sun is out
Your work involves you being in the outdoors or near/in the water 
You enjoy outdoor activities
You get headaches or migraines that is easily triggered by glare
You just had cataracts surgery and polarized sunglasses can offer additional protection.
You work in an open plan cubicle office and handle a lot of glossy documents.
